IPC: F22B1/02
Filed: 1981-02-28
Abstract: A steam generator having cold branch and hot branch zones defined, inside the secondary envelope, by vertical partitions separating the cold limbs from the hot limbs, and outside the secondary envelope by a skirt surrounding a portion of the latter on the cold branch side, forming therewith a space closed on its sides and at its lower portion while leaving a passage to the cold branch zone from the inside of the envelope. The space is open at the top so that recycled water can return to the bundle of U-tubes through both zones, but secondary feed water circulates for the most part in the cold branch zone. Recycled water may be distributed between the cold and hot branch zones, and the pressure in these zones may be balanced at the level of a horizontal, perforated tubular plate.

Title: X-y optical deflector
Inventor: MIURA AKIRA
IPC: G02F1/01
Filed: 1982-02-25
Abstract: PURPOSE:To obtain a titled optical deflector which is operated at a high speed and has high deflection efficiency, by placing a pair of optical deflecting elements whose light is deflected by heat applied to one face of a crystal element, in the right angle direction to each other, and fetching a laser light projected in parallel to a heated face of one element, through the other element. CONSTITUTION:The side of comb-tooth electrodes 21, 22 of a crystal element 10 is heated by heating of the electrodes 21, 22, and a face 23 of the opposite side of the electrodes 21, 22 is held at a constant temperature. When the crystal element 10 is in a heated state, an interval between lattices is wide in the vicinity of the electrodes 21, 22, accordingly, the inter-molecular density is small, the opposite side 23 becomes narrow in its interval, and the density becomes large. The larger a refractive index of light passing through a transparent crystal body is, the larger the density is, therefore, the projected laser light is deflected and emitted as shown by a full line. When 2 pieces of such optical deflecting elements 100, 100' are used, and also these 2 pieces are used in the right angle direction to each other, a signal polarized in the X axis and Y axis directions can be fetched.
